Title: Improvements in and relating to the carrying out of Catalytic Operations and more particularly to the Conversion of Unsaturated Fatty Acids and their Glycerides into Saturated Bodies.
IPC: B01J23/70
Filed: 1912-02-24
Granted: 1913-05-26
Abstract: 4702. Boberg, T., and Techno-Chemical Laboratories. Feb. 24. Catalytic materials and processes.-A catalytic agent for use in the hydrogenation of organic substances, particularly unsaturated fatty acids and their glycerides, is prepared by reducing with hydrogen a metallic compound under such conditions that in the resulting catalyst the metal exists wholly or mainly as one or more suboxides; for example, in the case of nickel as a compound containing less oxygen than is contained in NiO. The reduction is carried out in an inclined rotary tube with a counter current of hydrogen, and the preferred range of temperature is from 230 to 270‹ C. The product may be used at once, or may be allowed to oxidize slowly, for instance, by collecting in water, filtering off, and allowing to dry in air or in an atmosphere of hydrogen, which is slowly replaced by oxygen or air. To prepare this catalyst for use, it is heated in hydrogen to about 180‹ C., or it may be treated with hydrogen when in suspension in a suitable liquid. Or the sub-oxide catalyst may be prepared by complete reduction of the nickel oxide, and oxidizing this product in air or oxygen diluted with an inert gas to avoid local overheating. The catalyst may be supported on an inert support, which may be finely divided.

Abstract: 6418. Austin Motor Co., and Austin, H. March 15. Latches, sliding.-To avoid the necessity for the latch spindle passing completely through the door of a motor-car &c., and thus reducing the space available for the sliding sash, the actuating-means for the latch for one or both sides of the door is placed in the door-jamb. In the form shown in Fig. 2, the inside handle C actuates a spindle and follower c on the door, while the outside handle D is on a spindle d mounted in the jamb and carrying a follower d<2> operating against the nose of the bolt. In a modification, both the inside and outside handles are on the spindle d. In another form, the bolt A is mounted in the jamb, and the inside handle is carried by the door and acts on the nose of the bolt. A sliding plunger may be used for pressing back the bolt.

Granted: 1912-08-08
Abstract: 9213. Porzig, K. April 18. No Patent granted (Sealing fee not paid). Supports for velocipedes comprise a pivoted member 1 which in the operative position holds the rear wheel clear of the ground, a lever 3 which can be swung into engagement with the member 1 when this is in the operative position, a key-operated tumbler 6 adapted to lock the lever in engagement with the member 1, and a pivoted leg for holding the forward part of the cycle clear of the ground. The supporting-member 1 comprises a pair of legs which are pivoted to brackets clipped to the frame, the legs being connected to the brackets by springs 2 which tend to hold them either in a nearly vertical or a nearly horizontal position. In the construction shown, two levers 3 of U-section are provided, the levers being connected to their brackets by springs 4 similar in action to the springs 2. In the operative position the hooked ends of the levers 3 engage adjustable abutments 5 on the legs 1, and a tumbler 6 in one of the levers engages a notch in one of the legs. The tumbler is held in the locking - position by a spring 7 and can only be rotated out of this position with the aid of a key. The leg 8 for supporting the forward part of the machine is forked at its upper end 9 and is mounted on a perforated bracket, a stud 12 carried by a plate spring being adapted to enter the perforations in the bracket for the purpose of locking the leg in its operative or inoperative position. A spring 10 connected to the leg tends to hold it alternatively in its two positions. In a modification, Fig. 6, the leg for supporting the forward part of the cycle is a U-shaped member 14 pivoted to clips 15, one of which carries a spring catch 18 adapted to engage one limb of the leg in the operative position. The leg is held in its inoperative position by a clip 20.

Granted: 1913-12-18
Abstract: 88. Beemer, F. Jan. 1. Keyboard switches; interlocked switches. - A set of interlocked plunger-operated switches is employed in combination with electro - mechanical change - gear mechanism on automobiles. A separate switch A<8>, B<2> is provided for each desired gearchange, each switch comprising a stem A<2> with a cam-surface A<10> and a recess A', an operating-plunger A<3>, and a retracting - spring, as shown, which normally maintains the switch open. When any plunger A<3> is depressed, its cam-surface A<10> engages a sliding locking-plate C common to all the switches and presses it to the left against the action of a spring C<2>. Further depression causes the recess A‹ to register with the plate C, which is returned by its spring C<2> and locks the switch in the closed position. If any other plunger is depressed, its cam-surface shifts the locking-plate as described above, thus allowing any switch previously locked to be opened by its retracting-spring, the switch under operation, however, being retained closed by the locking- plate. The switch device is shown arranged for three speeds and reverse represented by the first three plungers and the last, respectively. The reverse plunger is covered by a spring- pressed hinged cap D which must be turned back before the plunger can be operated. The plunger A<3> adjoining the reverse plunger is a releasing-plunger only. It is not provided with a contact or with a recess A<9>, but only with a cam-surface for operating the locking-plate to release all the switches.

Abstract: 5467. Philip, A., and Steele, L. J. March 4. Explosive and combustible gases, detecting.- Relates to detectors of combustible gases of the kind in which an electrically-heated wire of catalytic material is employed and the change of resistance of the wire in the presence of combustible gas gives an indication on a galvanometer, for example detectors in which active and inactive wires form arms of a wheatstone bridge or are arranged in parallel and each in series with one winding of a differential galvanometer. Means are provided for initially balancing the branches of a circuit including active and inactive wires, for equalizing heat-losses by radiation, and for permitting inspection of the wires. As shown in Fig. 2, active and inactive wires 6, preferably arranged alternately to form a wheatstone bridge, are enclosed in tubes 1, 2, and when heated electrically cause a draught therethrough. The wires are joined by strips 9 of german silver, platinum, platinumsilver alloy, &c. mounted on insulating-blocks 10; the battery or galvanometer is connected to the strips 9 through springs 11 carried by a sleeve 13 which with the springs 11 may be moved by a screw to balance the arms of the bridge. Only one slidable connexion may be used. The strips 9 may be arranged in arcs and the adjustment effected by a rotatable member. The radiation effect may be balanced by the provision of an opening in the tubes adjustable by a sliding sleeve or by piercing a suitable number of holes 17 preferably at the top and bottom of the tube surrounding the inactive wires. The apparatus may be mounted in an outer casing which may be filled with gas to be tested as by a pump. A window 18 may be provided in the tube 1, and a similar window with a removable cap in the outer casing, to enable the active wires to be watched so as to avoid excessive heating. For preliminary tests, a separate piece of catalytic material may be provided, or a series of such pieces in the form of cartridge or other fuses may be provided, each adapted to be put in circuit as required.
